Answer:

<em>16.5 gallons per minute.</em>

Step-by-step explanation:

The given table is:

\begin{center}\begin{tabular}{ c c } Time(minutes) & Water(gallons) \\ 1 & 16.50  \\  1.5 & 24.75  \\   2 & 33   \\\end{tabular}\end{center}

We are given this linear function in the form of table.

Let 't' be the time and W(t) be the function with which the gallons of water are changing with time.

We can use slope intercept form to find the equation.

y=mx+c

Slope of a function:

m=\dfrac{y_2-y_1}{x_2-x_1}

x_2 = 1.5\\x_1 = 1\\y_2 = 24.75\\y_1 = 16.50

m=\dfrac{24.75-16.50}{1.5-1}\\\Rightarrow m =16.5

This slope is the constant of proportionality.

i.e. the rate at which the number of gallons are changing per minute.

So, the answer is <em>16.5 gallons per minute.</em>

Graph the first six terms of a sequence where a1 = 2 and r = 4.
zavuch27 [327]
We are given with
a1 = 2
r = 4

These are components of a geometric series. The first term is 2 and the common ratio is 4. To get the first six terms, we use the formula:
an = a1 r^(n-1)
a1 = 2 (4)^(1-1) = 2
a2 = 2 (4)^(2-1) = 8
a3 = 2 (4)^(3-1) = 32
a4 = 2 (4)^(4-1) = 128
a5 = 2 (4)^(5-1) = 512
a6 = 2 (4)^(6-1) = 2048

4 red balls 4 white balls what is the probability of drawing at least 1 red ball if two balls are drawn
vodomira [7]
The probability of drawing exactly one red ball is given by:
P(1\ red\ ball)=\frac{4C1\times4C1}{8C2}=\frac{16}{28}
the probability of drawing two red balls is given by:
P(2\ red\ balls)=\frac{4C2\times4C0}{8C2}=\frac{6}{28}
The probability of drawing at least one red ball is:
P(1 red ball) + P(2 red balls) = 16/28 + 6/28 = 11/14.
 The answer is \ \frac{11}{14}
